Postweld Heat Treatment Code Exemption - Pt 1 - TWI

Post-weld heat treatment (PWHT) is applied to steel assemblies primarily to reduce the likelihood of brittle fracture by reducing the level of tensile welding residual stresses and by tempering hard, potentially brittle, microstructural regions. For large steel assemblies in particular, PWHT can be an expensive operation, and there is thus an economic incentive to avoid PWHT, wherever possible. Whether PWHT is necessary depends on the fracture toughness at the minimum service temperature, the stress levels an…See more on twi-global.comsp.info PWHT Welding Preheating System for Shipboard And Steel ...Their main applications are pipeline heat, pre-weld heat, post-weld heat treatment, stress relief, injection mold heating, annealing, etc. Pre-heat:for coating, bending, fitting&unfitting, weld.
